2. Flush Bolts
Flush bolts are typically installed on the leading and bottom edges of the inactive door panel.

- Benefits: Keeps the non-active door safely in place, allowing the active door to lock against it safely. They stay concealed from view when the doors are closed.
3. Mortise Locks
A mortise lock fits inside a rectangle-shaped pocket (mortise) cut into the edge of the door.
- How it works: It houses both the lock system and the deadbolt within a single, heavy-duty metal box, using exceptional strength compared to basic cylindrical bored locks.
4. Surface-Mounted Slide Bolts

| Mortise Lock | High | High | Moderate | Standard wooden French doors |
| Flush Bolts | Moderate | Medium (Manual levers) | Low | Securing the non-active panel |
| Surface Area Slide Bolts | Low to Moderate | Low (Manual operation) | Low | DIY retrofits or interior doors |
| Smart French Locks | High | Very High (App/Keypad) | High | Modern homes, wise home integration |
Key Features to Look for When Buying French Door Locks
